图4. 不同光照和温度条件下红松的平均萌发时间(平均值±标准误)。L0、L20、L200代表光照强度分别为0、20、200 μmol·m-2·s-1。不同大写字母表示相同光照下不同温度之间萌发率差异显著(p ≤ 0.05); 不同小写字母表示相同温度条件下不同光照之间萌发率差异显著(p ≤ 0.05)。
Fig. 4. Mean germination time (MGT) of Pinus koraiensis seeds from three provenances under different light and temperature conditions (mean ± SE). L0, L2 and L200 represent 0, 20, 200 μmol·m-2·s-1 light intensities, respectively. Different uppercase letters indicate significant differences between different temperature conditions under the same light intensity (p ≤ 0.05); different lowercase letters indicate significant differences between different light intensities under the same temperature condition (p ≤ 0.05).
